To a solution 2,4-dichloro-5-fluoropyrimidine (150.0 mg, 0.898 mmol) in 2-propanol (4.00 mL) at RT was added N-ethyl-N-isopropylpropan-2-amine (0.469 mL, 2.70 mmol) followed by 3-(4-fluorophenoxy)azetidine hydrochloride (183 mg, 0.898 mmol). The resulting reaction mixture was stirred at RT for 1 h and concentrated. Purification of the crude using MPLC (25 g cartridge, 40 g column, 0 to 60% EtOAc-hexanes) gave 2-chloro-5-fluoro-4-(3-(4-fluorophenoxy)azetidin-1-yl)pyrimidine (240.6 mg).
